- Specification of Letters Patent.

Application filed Kay '1, 1909. Serial No; 494,638.

To all whom it mag concern:

Be it known that I, John C. MCLAUGHLIN, a citizen of the United States, residing in J ersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to guides for thccar: riage stops of the tabulating'mechanism of a writing machine.

It has been proposed to form a slot-guide in two parts, and in each art to form nicks to receive a series of ree s, which separate the slots from one another, and to use a cap to hold said two parts and said reeds in position.

The principal object of my inventionis to make a simple, inexpensive and extremely strong construction, which because of its strength will stand the pounding action of stops and guides.

In the accompanying drawings, Figure 1 is a perspective new of an improved guide, a series of stops being tion in said guide. Fig. 2 shows the rude reversed to accommodate a differently placed set ofstops. Fi 3 is a perspective new of the members of t 1e two-part guide separated. Fig. 4 is'asectional elevation of sufficient portion of a typewriting machine to illus- Fig.5 is atrate the present lmprovements. plan of a blank from which is made one of. the parts seen at Fig. 3

Sto s 1 in the form of vertical rods are mova le u by means of levers 2 fulcrumed upon a r0. -3 and having keys 4 at their forward ends. .These stops are thrust up into the paths of stops 5-secured upon the rack bar 6, which is usually supported upon a paper carriage (not shown). cm s the stops 1 are fitted in slots 7 f0 sued in a two-part guide, one part. marked g} the other 9, and each having at its ends roles 10, to receive screws 11, by which it is held upon the top of a vertical bracket 12 of the usual construction.

incisions are also made at 7 b at the sides of the tongue, and to the same depth asthe incisions 7*, thus producing a $81168 of's1m1- bar 8, are secure shown in section in posrgra At their upper guide is formed in its e ge with a deep recess 15, in the bottom of which is a series of nicks 16,'in which lit the ends of the prongs 14. It will be seen that thesetwo' parts 8 and 9 may be easily laced together, with the prongs 14in the nicks 16, and readily fastened and placed by the screws 1 1 upon the bracket 12. All necessity of forming, mounting andsecuring a set of oose reeds is avoided, while a capwoe is rendered unnecessary. Moreover, t e prongs 14, being integra with against breaking or shearing action, due to the impact of the carriage when arrested b the cooperation of the stops 1 and 5. ig. 1 shows a set of sto s fitted in the slots'between the prongs 14. it will be seen that the guiding slots 7 are formed nearer one endof the guide than the other, and the guide is made reversible, so

the

that it-may be turned end for end from the osition'atFi 1 to the position at Fig. 2.

may be employed, many operators requiring only five decimal stops, and some wishing to use the group seen at Fig. 1, and others to use the grou seenat Fig. 2.

Having t us described claim:

1. A two-part guide for a series of carriage stops, onepart formed with a series of inte prongs and the other part formed with nicks to. receive the ends of said prongs.

my invention, I

2. A two-part guide for a seriesioj carriage sto s, one part formed with a series of-integra prongs which project beyond the edge ofsaid part and the other part formed with a.

recess in the bottom of which are provided. nicks to receive the ends of said prongs.

3. A reversible two-part guide for a series of carriage stops, one part formed with a series of integral prongs and the other part formed with nicks to receive the ends of said prongs, said prongs being formed near'one end of said guide, so that by reversing the guide end for end the prongs will be caused to occupy an opposite position upon. the machine, for the purpose specified.
